Abstract: A magnetic element can be configured as a data writer with at least a write pole contacting a yoke and having an air bearing surface. The write pole may be shaped to match a paddle surface of the yoke that extends perpendicular to the air bearing surface and facing parallel to the air bearing surface.

Abstract: A writer assembly having two separately driven write coils allows a combined write field generated by the writer assembly to be fine turned and optimized for a particular application. Two preamplifiers may be incorporated into a printed circuit board in order to separately drive the write coils. In other implementations, there may be more than two write coils and corresponding preamplifiers.

Abstract translation: 具有两个单独驱动的写入线圈的写入器组件允许由写入器组件生成的组合写入字段对于特定应用进行精细转换和优化。 为了单独驱动写入线圈，可以将两个前置放大器并入到印刷电路板中。 在其他实现中，可以存在多于两个的写入线圈和相应的前置放大器。
